How do I connect this to my soundboard?

Simple! For beginners, we recommend connecting your device to your soundboard using a 1/8" headphone to dual 1/4" jacks. The Click in Prime is automatically panned to the LEFT, and the instrument Tracks are panned RIGHT. For more advanced users, we recommend using the Track Rig interface. Track Rig gives you 8 XLR outputs that you can send Prime tracks out of.
